Daemonize strobe thread; normalize config booleans

Mark StrobeLED threads as daemon so they won't block OctoPrint shutdown and add SoftwareUpdatePlugin to the plugin class registration. In the frontend, switch door icon classes to FontAwesome and make handling of boolean-like settings robust by treating 1, "1", and true as enabled; introduced a helper isEnabled and applied it across navbar and settings so tower, strobe, and door-lock toggles initialize and subscribe correctly.
